TIRE-ARMOR.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed Apri121, 1914. Serial No. 833,499.

1 0 all whom it may concern Be it known that I, THoMAs 'P. MARco'r'rE, acitizen of the United States, residing at \Vest Poland, in the county ofAndroscoggin and State of Maine, have invented certain new and usefulImprovements in Tire- Armor; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to new and useful improvements in tires and moreparticularly to attachments therefor which comprises armor that may bereadily and easily attached to tires and will prevent punctures andwear.

An important object of my invention is to provide tire armor of thecharacter described which comprises a plurality of segmental armorsections each being U-shaped in cross section and arranged to incase thetire, said sections being arranged to be fitted together to form acasing for the tire.

Another important object of my inven tion is to provide novel means forclamping the sections along their meeting edges, which projects beyondthe surface of the armor and act to prevent skidding.

Another important object of my invention is to provide a tire of thecharacter described which is simple as to construction, reliable andellicient in operation, capable of being readily attached and detachedand which is cheap to manufacture.

The above and additional objects are accon'iplished by such means as areillustrated in the accompanying drawings described in the followingspecification and then more particularly pointed out as claimed.

\Yith reference to the drawings, wherein I ha vc illustrated thepreferred embodiment of my invention as it is reduced to practice, andthroughout the several views of which similar reference numbersdesignate corrcspoiuling parts, Figure 1 is a side elevation showing myimproved armor in as scuibled operative position, Fig. 2 is a detailperspective -view of one of the armor sections, Fig. 3 is a detailperspective view of one of the clamping plates, Fig. a is a verticalsectional view taken through Fig. 1. and Fig. 5 is a detail perspectiveview of one of the clamping members.

Referring to the drawings by characters of reference, the numeral 1designates as an entirety, a vehicle Wheel which comprises the usual hub2, spokes 3 and felly 4.

it tire 5 is mounted upon the felly 4: and as illustrated is of thesolid cushion type. In this connection it is to be noted that myinventlon is applicable to pneumatic tires as Well as solid.

My improved armor comprises a plurality of segmental sections 6 eachbeing U-shaped. Each of the sections 6 is provided adjacent its end uponopposite side edges thereof with recesses 7, to provide spaces toaccommodate fastening means when the sections are fitted in engagementwith each other along their edges upon the tire.

As a means for securing the sections 6 upon the tire I employ bolts 8that are inserted transversely through the felly 4 and extend into therecesses 7 of the sections, the sections being previously fitted uponthe tire so that the sides thereof overlap the sides of the felly l asclearly shown in Fig. 4 in the drawings. Nuts 9 are turned upon theunheaded terminals of the bolts 8.

. As a means for securely holding the sections (3 in proper engagementwith each other and in position upon the tire, I employ U-shapedclamping members 10 that are provided with their longitudinal slots 11adjacent their ends. These clamping members 10 are fitted upon thesections G'so as to overlie the meeting edges of the sections thusproviding a tight joint. The bolts 8 are inserted through the slots 11,said slots being positioned in registration with the openings formed bythe recesses 7. The members 10 project beyond the surface of thesections 6 of the armor .and provide an irregular tread surface whichwill serve to prevent skidding and enable the wheel to grip in startingor stopping.

I also provide segmental clamping plates 12 having apertures 13 adjacenteach end. The clamping plates 12 are positioned in en gagcment with theend portions of the menr hers 10 and receive the bolts 8 through theapertures 13. These clamping plates 12 serve to securely hold theclamping members 10 and sections (3 comprising the armor in the properposition upon the tire. It will be noted that the sections 6 fit snuglyabout the felly and tire and that the clamping memhere 10 snugly clampthe members 6 at their meeting edges. This arrangement insures theproper protection of the tire and prevents derangement of the armorincident to shown the clamping plate 12 operating in' connection withtwo of the members 10 1t is to be understood this arrangement may bechanged as desired.

The forming of the recesses 7 will enable the reception of the bolts 8,dispenses with fastening means for the difi'erent elements of the deviceand serves to hold the members 6 securely in place. The recesses 7 andslots 11 provide for the tangential movement occasioned under drivingstrain and when the vehicle is at rest and the weight thereof placedupon the tire thus permitting the necessary resilient action to preventderangement of the armor. a

' In practice, I have found that the form of my invention, illustratedin the drawings and referred to in the above description, as thepreferred embodiment, is the most efficient and practical; yet realizinthat the conditions concurrent with the a 0 tion of my device willnecessarily vary, I esire to emphasize the fact that various minorchanges in details of construction, proportion and arrangement of partsmay be resorted to, when required, without sacrificing any of theadvantages of my invention, as set forth.

What is claimed is? 1. A tire armor comprising a plurality of segmentalsections each being provided adjacent its ends with recesses upon theopposite side edges thereof, U-shaped clampin members mounted upon andengaging sai sections adjacent their meeting edges and provided withlongitudinal slots alinin with said recesses and bolts extende throughsaid slots and recesses, said bolts being slidable with relation to therecesses and slots to .permit tangential movement of said sections.

2. A tire armor comprising a plurality of segmental sections adapted toincase a tire and engage thesides of the felly of a wheel, said sectionsbeing arranged in engagement with each other along their end edges, U-shaped clamping members mounted upon and engaging said sections adjacenttheir end edges, said clamping members covering the meeting edges ofsaid sections and being provided with longitudinal slots at their ends,said sections each having recesses upon their side edges adjacent theends thereof, said recesses being disposed in alinement with said slots,bolts inserted through the slots, recesses and felly of the wheel, saidboltsbein slidable with relation to said recesses an segmental clampingplates arranged upon opposite sides of said sections and clampingmembers, said bolts extending through said clamping plates.

In testimony whereof I aflix my signature in presence of two witnesses.
